Does off-farm employment contribute to agriculture-based environmental pollution? New insights from a village-level analysis in Jiangxi Province, China

This study examines the conventional wisdom that off-farm employment contributes to environmental pollution by increasing the use of agro-chemicals. In order to analyse the role of household decision making and village factor markets in more detail, we run simulations with a hybrid farm household/village computable general equilibrium model that is applied to a village in Northeast Jiangxi Province. We find that the negative lost-labour effect of off-farm employment on agricultural incomes is much stronger than the (small) positive income effect. As a result of reduced labour resources and increased leisure consumption, farm households reduce the intensity of rice cultivation as well as the production of (especially) cash crops. The shift in production activities is stronger for migration than for off-farm employment, because migrants cannot combine off-farm work with onfarm work, and because migration reduces the village market price of oxen services. The shift towards less intensive rice production means that off-farm employment (and migration in particular) reduces the levels of chemical inputs and manure used in agricultural production. The decline in fertilizer input is much larger than the decline in manure use, because manure is a nontradable commodity and is applied only once per year. We therefore conclude that migration and, to a lesser extent, local off-farm employment lead to lower incomes from agricultural production, but have benign effects on environmental quality.     

Rural households' decisions towards income diversification: Evidence from a township in northern China

Economic reforms in rural China have brought opportunities to diversify both within-farm activities and off-farm activities. Participation in these activities plays an important role in increasing rural households' income. This paper analyzes the factors that drive rural households and individuals in their income-source diversification choices in a Northern China township. At the household level, we distinguish three types of diversification as opposed to grain production only: within-farm (non-grain production) activities, local off-farm activities, and migration. We find that land availability stimulates on-farm diversification. Local off-farm activities are mostly driven by households' asset positions and working resources, while migration decisions strongly depend on the household size and composition. At the individual level, we analyze the determinants of participation in three different types of jobs as compared to agricultural work: local off-farm employment, local self-employment and migration. We find a clear gender and age bias in access to off-farm activities that are mostly undertaken by male and by young people. The households' asset positions as well as village networks are found to strongly affect participation in off-farm activities.     

The role of off-farm employment in the rural energy consumption transition — A village-level analysis in Jiangxi Province, China

Energy consumption in rural areas in China is characterized by high consumption of fuelwood, straw and other biomass. Off-farm employment can play an important role in the transition towards more sustainable sources of energy by increasing rural household incomes and reducing the amount of labor available for biomass collection. The purpose of this paper is to examine the impact of off-farm employment on rural household energy consumption choices, and to disentangle the various causal relationships that play a role in this respect. To this end, a hybrid farm household/village computable general equilibrium (CGE) model is used that has been calibrated for a remote village in Northeast Jiangxi Province where fuelwood is the main source of energy. The model takes into account nonseparability of farm household production and consumption decisions as well as linkages within the village between households involved in off-farm employment and households with no members working off-farm. Contrary to previous research for a richer region in rural China, we find that fuelwood is not an inferior good. The positive impact of more food consumption on fuelwood collection more than compensates the higher leisure demand associated with higher incomes. Shifts in production activities and in prices on village factor markets caused by increased labour scarcity (the lost-labour effect of off-farm employment), on the other hand, cause a reduction in fuelwood collection and consumption. This lost-labour effect is much stronger for migration than for local off-farm employment, because the latter can more easily be combined with on-farm work and fuelwood collection. For local off-farm employment the income effect dominates the lost-labour effect, resulting in a positive overall impact of higher off-farm participation on fuelwood consumption. For migration, on the other hand, the income effect and the lost-labour effect are almost equal in size. Hence, the amount of fuelwood collected and consumed does not change much when households participate in migration. The final conclusion is therefore that increased off-farm employment opportunities do not promote the transition of rural energy use in the poorer regions of rural China.     

INCOME INEQUALITY IN THE PHILIPPINES, 1961–91

Household income inequality in the Philippines remains high and the trends for three decades have been fairly stable except for a sharp decline in the mid-1980s. Gini coefficient of income inequality has been consistently close to 0.50. Urbanization and education of household head are the most important factors determining the level of income inequality while the contribution of age of head is limited. The increase in the number of urban households results in an increase of overall inequality while the increase in the number of household heads with a college education tends to decrease the inequality. Among the household income sources, wage income is the largest contributor to total income inequality. Wage rate inequality appears to be a major source of wage income inequality.     

Choices between different off-farm employment sub-categories: An empirical analysis for Jiangxi Province, China

This paper analyzes the relative importance of four sub-categories of off-farm employment, and the factors driving participation of individuals in these sub-categories for three villages in Jiangxi Province. We find that migration is the most important type of off-farm employment, while agricultural wage employment is a minor activity. Migrant remittances are smaller than household incomes earned from self-employment and local non-farm employment. The results of a multinomial probit analysis explaining off-farm participation decisions show that presence of young children in a household restrains participation in migration, while the presence of elderly persons and a higher level of education stimulate migration. Local wage employment and self-employment are not affected by these factors. The gender bias in access to off-farm employment is largest for agricultural employment and local non-agricultural employment. Land scarcity stimulates participation in migration and local non-agricultural employment, while possibilities to rent land out to other farmers stimulate only migration. The paper ends with policy suggestions for promoting off-farm employment within the own region and for altering the criteria for land distribution to rural households.     

Income Strategies Among Rural Households in Mexico: The Role of Off-farm Activities

Off-farm activities generate on average more than half of farm households' incomes in the Mexican ejido sector. Participation in these activities helps reduce poverty and contributes to greater equality in the distribution of income. This paper analyzes the determinants of access to off-farm sources of income across households. We find that education plays a major role in accessing better remunerated nonagricultural employment. Adults of indigenous ethnic origin suffer from an educational lag and have less access to off-farm nonagricultural employment than non-indigenous adults at identical educational levels. The regional availability of off-farm employment strongly affects participation. In addition, women are differentially limited by distance to urban centers in their ability to gain off-farm employment.     

Do Chinese farmers reinvest in grain production?

Grain production is affected by the relocation of farm household labour from on-farm to off-farm activities and by an increase in the investment in grain production as a result of increase in farm household income that occurs along with such a labour shift. This study uses a recent farm household survey data to examine whether Chinese grain households do reinvest in grain production. It has found that household income growth contributes to higher investment in grain production although a higher share of non-agricultural income has a negative effect. The authors' other research has found a negligible direct impact of farm to non-farm labour transfer on grain production. We may conclude that in the near future, the total impact (direct and indirect) of labour transfer from farm to non-farm production on grain output is expected to be positive. In the long run, in may become negative when more and more labour shifts out of grain production and marginal product of labour becomes positive.     

Cooperative patronage: The National Smallholder Farmers' Association of Malawi in Kasungu District

This paper estimates the determinants of farmers' decisions to join a rural producer organisation, the National Smallholder Farmers' Association of Malawi (NASFAM), in Kasungu District. Data for the study were collected in June and August 2003 using household-level questionnaires and stratified random sampling, where strata were membership status and gender. Probit analysis of 250 farmers shows that off-farm sources of income, distance of the farmer's household from Kasungu District centre, age of the farmer, tobacco farming, education, household level land holding and gender determined the decision to join NASFAM. These results suggest that farmers should be informed of the potential benefits of participating in rural development efforts, and that rural communication and information infrastructure should be improved so as to reduce the costs of information access and transactions in general, if participation in organisations such as NASFAM is to be enhanced.     

Off-farm employment and time allocation in on-farm work in rural China from gender perspective

This paper sheds light on how the growing number of off-farm employees affects the labor allocation of female and male left-behind farmers in the Chinese agricultural sector. We find no direct effect of off-farm employment on left behind workers' total working time in farming, nor do we observe a gender difference in this respect. However, we do find that increasing off-farm work is associated with fewer days worked on staple crops, and in the harvesting and sales stages of the production process. Hiring labor and buying agricultural services also impact left behind workers' time allocation. Moreover, we find that in China, contrary to several other developing countries, there is no trend towards a feminization of agriculture, but rather a tendency in the reverse direction.     

Will remittances suppress or increase household income in the migrant-sending areas? Modeling the effects of remittances in rural China

There are ongoing debates about whether remittances suppress or increase household income in the migrant-sending areas. The literature has not explained the heterogeneous results in a unified framework. This paper proposes a new concept, remittance capitalization potential (RCP), to conceptualise the possible switch between suppression effect and incentivization effect of remittances in the migrant-sending areas. The theoretical model reveals that remittances suppress household income in the migrant-sending areas when the RCP level is below a certain threshold, while remittances help increase household income in the migrant-sending areas when the RCP level is above a certain threshold. Moreover, the factors that affect the RCP level, such as the level of household human capital, ultimately determine whether remittances exert suppression or incentivization effect in the migrant-sending areas. Using China Family Panel Studies (CFPS) data, this paper adopts the method of instrumental variables to estimate how the level of household human capital alters the effect of remittances on household income from agricultural production in rural China. The models show that in the households with the head agricultural producers who are illiterate or semi-literate, the remittances suppress the agricultural income significantly. In the households with the head agricultural producers who are literate, however, the impact of remittances on the agricultural income switch to be positive significantly. The robustness tests not only support the results from the base models, but also confirm that the level of household human capital works as an influencing factor of RCP and determines whether remittances suppress or increase household income in the migrant-sending areas.     

Incomplete property rights, exposure to markets and the provision of environmental services in China

This paper uses data from a 2003 rural survey to examine the determinants of household provision of environmental services under China's Sloping Land Conversion Program (SLCP), the largest payments for environmental services program in the developing world. The paper examines the determinants of plot-level survival rates of program-planted trees and grasses. It finds that household rights over retired land as well as autonomy in program decision-making (which we argue on the basis of supportive evidence are plausibly exogenous to post-retirement outcomes) have important and potentially countervailing impacts on the provision of environmental services targeted by the program. Households permitted to select what to plant obtain better program outcomes, but do not make the choices that the government would like them to, while those permitted to decide what land to retire perform worse. The analysis also finds that households more vested and experienced in agriculture and with less exposure to off-farm labor markets fare better in managing their planted trees. Significant learning-by-doing effects are also evident, suggesting that greater technical support to farmers could improve outcomes and lower program costs.     

Off-farm employment and grain production change: New evidence from China

How does off-farm employment affect grain production? Previous research findings are inconsistent. This paper provides a general theoretical framework to explain the effect of off-farm employment on grain production and consider that the effect is non-liner. The empirical results show that off-farm employment decreases grain production and insignificantly changes grain crop structure. Importantly, we find an inverted-U correlation between off-farm employment and grain production, meaning that off-farm employment will increase grain production when the off-farm labor supply is relatively low and will decrease grain production when the off-farm labor supply is relatively high. Further, we investigate the heterogeneity of the causal effect in the destinations of off-farm employment, household's land scale, land features, household location, and household aging.

The Invisible Hand of Rain in Spending: Effect of Rainfall‐Driven Agricultural Income on Per Capita Expenditure in Ghana

This paper uses a nationally representative household pseudo‐panel dataset for Ghana, a rain‐fed agriculture economy, to investigate whether there is a positive relationship between rainfall‐driven agricultural income and household per capita expenditure. By using the Two Stage Least Squares Instrumental Variable (2SLS‐IV) estimator, it is found that a fall in rainfall‐driven agricultural income leads to a decrease in per capita expenditure. The results show that the gender and the locality of the household head matter in the response of per capita expenditures to rainfall‐driven agricultural income. Female‐headed and rural households are more vulnerable to rainfall‐driven agricultural income changes. The expenditure disaggregation indicates that female‐headed households significantly reduce per capita non‐food expenditure in times of rainfall‐induced agricultural income decrease whilst the response of male‐headed households focuses more on reducing per capita food and remittance expenditures.     

The Determinants of Nonfarm Income Diversification in Rural Peru

This paper shows that in Peruvian rural areas, there has been substantial growth over the past decade in household employment outside of own-farming. At present 51% of the net income of rural households comes from these off-farm activities, and thus they certainly cannot be considered as “marginal.” The reasons households diversify their incomes are several. Access to public assets such as roads and private assets such as education and credit is an important factor in diversification. Increasing access to these assets will help rural households to increase their self-employment as well as wage employment in the nonfarm sector.     

Transaction costs and crop marketing in the communal areas of Impendle and Swayimana,KwaZulu-Natal

High transaction costs are detrimental to the efficient operation or existence of markets for inputs and outputs. The cost of information and the costs associated with the search for trade partners, the distance to formal markets and contract enforcement are likely to influence the marketing of food crops. This study hypothesises that the level of income generated from food-crop sales by small-scale farmers in the Impendle and Swayimana districts of KwaZuluNatal is influenced by transaction costs and certain household and farm characteristics. Regression analysis shows that the depth of marketing methods is significantly influenced by transaction cost proxies, such as cooperation with large commercial farmers and ownership of means of transport. Results from a block-recursive regression analysis show that the level of crop income generated is determined by the depth of marketing methods, the size of allocated arable land and off-farm income. Households with lower transaction costs, sizeable allocated land and off-farm income can be expected to generate higher income from food crops. Investment in public goods such as roads, telecommunications and an efficient legal system (to uphold commercial contracts), as well as farmer support services (input supply, extension, marketing information and research), would probably raise farm and non-farm income by reducing transaction costs. This would increase the effective demand for locally produced goods and services, thus contributing to rural employment and livelihoods within rural communal areas.

Characteristics examined include sector in which the household head derives most of his or her income, the age, sex, occupational and educational status of the household head and, in the case of agricultural households, land owned and occupied.     

THE IMPACT OF GREEN REVOLUTION ON RICE PRODUCTION IN VIETNAM

The current paper reviewed the development of the Green Revolution in Vietnam, using long‐term regional yield and modern variety adoption statistics, as well as household data collected in 1996 and 2003. The present study indicates that the Green Revolution began in irrigated favorable areas and spread to the less favorable areas in Vietnam such as in other Asian countries. What is unique in Vietnam is that although the Green Revolution ended in the mid‐1980s in the Philippines and Indonesia, it has still been sustained as of 2003. Our analyses revealed that such growth had been supported by continuous improvements of modern varieties by regional research institutes. The varieties imported from China have contributed to the Green Revolution in northern Vietnam and those developed by the International Rice Research Institute in southern Vietnam. The national agricultural research systems have also played a critically important role in developing location‐specific and appropriate technologies.
